Description

Technical Field

[0001] This utility model relates to the field of sealing rubber ring technology, specifically to an inner lining sealing rubber ring. Background Technology

[0002] A rubber seal is an annular cover consisting of one or more parts, fixed to one of the bearing rings or washers and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign matter intrusion.

[0003] Existing patent CN204878727U discloses a high-pressure sealing ring, relating to the technical field of elastic sealing devices. It includes a sealing ring body with a shaft hole at its center, an outward-opening groove on the outer side of the shaft hole, an outward-extending boss on the outer side of the groove, and three or more sealing ring mounting holes along the edge of the sealing ring body.

[0004] The aforementioned patents or existing sealing rubber rings have the following problems:

[0005] The existing sealing rubber ring has a simple structure, and it is not easy to position it when it is lined into the pipe. This may cause the rubber ring to tilt or collapse. When two pipes are connected, the bolt holes need to be aligned. During this process, the pipe may be rotated and adjusted, which may twist the rubber ring and cause deformation, affecting the sealing performance. Utility Model Content

[0006] The purpose of this invention is to provide an inner-lined sealing rubber ring to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an inner lining sealing rubber ring, comprising a ring body, a shaping ring disposed in the ring body, a retaining ring disposed at the end of the ring body, a pressure ring disposed on the surface of the ring body, and a positioning ring disposed on the surface of the retaining ring.

[0008] Preferably, the wall thickness of the ring is greater than five millimeters.

[0009] Preferably, the corners of the positioning ring are rounded.

[0010] Preferably, the positioning ring has a pressure port.

[0011] Preferably, there are two pressure rings, and the middle part of the pressure ring is hollowed out.

[0012] Preferably, the protruding portion of the pressure ring is arc-shaped, and the pressure ring is inclined inward.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The ring is inserted into the pipe's docking port as an inner liner. Then, the ring is pushed into the pipe docking port. At this time, the positioning ring will be compressed and stuck in the pipe, so that the ring is positioned in the pipe, effectively preventing the ring from tilting and collapsing. When the pipes are docked, the docking pipes will come into contact with the protruding part of the pressure ring. Because the contact surface of the protruding part is small, it is not easy to drive the ring to rotate when the docking pipes are aligned with the bolt holes. This prevents the ring from twisting and deforming during pipe alignment. After the pipes are docked, they will squeeze the pressure ring and the ring body, so that the pressure ring and the ring body are sealed at the pipe docking point. Attached Figure Description

[0018] In the diagram: Ring body-1, shaping ring-2, retaining ring-3, pressure ring-4, positioning ring-5, and pressure port-51. Detailed Implementation

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an inner-lined sealing rubber ring, including a ring body 1, which is made of rubber. A shaping ring 2 is fixed in the ring body 1 and the ring body 1 wraps around the shaping ring 2. The wall thickness of the ring body 1 is five millimeters. The shaping ring 2 is used to improve the compressive strength of the ring body 1 and prevent the ring body 1 from being over-compressed. A retaining ring 3 is provided at the end of the ring body 1. The retaining ring 3 is used to cover the pipe connection and improve the sealing performance.

[0021] The surface of the ring body 1 is integrally formed with pressure rings 4. There are two pressure rings 4, and the middle of the pressure ring 4 is hollow. The protruding part of the pressure ring 4 is arc-shaped and the pressure ring 4 is inclined inward. When the two pressure rings 4 are under pressure, they can fill the space between the pipe and the ring body 1. The hollow middle of the ring body 4 has a better pressure-bearing effect and better elasticity to fill the space between the pipe and the ring body 1 when under pressure, thereby improving the sealing performance. When the pipe is connected, the protruding part of the ring body 4 can first contact the pipe surface. Because the contact area of ​​the protruding part is small, it is not easy to drive the ring body 1 to rotate and twist when the pipe is rotated and adjusted. The inward inclination of the pressure ring 4 can prevent it from being squeezed outward when under pressure.

[0022] The retaining ring 3 is provided with a positioning ring 5. The corners of the positioning ring 5 are rounded, which has the beneficial effect of quick docking. A pressure port 51 is formed in the positioning ring 5, so that the positioning ring 5 can be pressed and stuck in the pipeline for positioning.

[0023] Specifically, the ring 1 is inserted into the pipe docking port as an inner lining, and then the ring 1 is pushed into the pipe docking port. At this time, the positioning ring 5 will be compressed and stuck in the pipe, so that the ring 1 is positioned in the pipe, effectively preventing the ring 1 from tilting and collapsing. When the pipes are docked, the docked pipes will come into contact with the protruding part of the pressure ring 4. Since the contact surface of the protruding part is small, it is not easy to drive the ring 1 to rotate when the docked pipe is aligned with the bolt holes, thus preventing the ring 1 from twisting and deforming during pipe alignment. After the pipes are docked, they will squeeze the pressure ring 4 and the ring 1, so that the pressure ring 4 and the ring 1 are sealed at the pipe docking point.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
